LOL!
i guess the 'it' in "just do it" ramifies into compromises in other avenues of conjugal life than just/only sex (going for sex to save the marriage). compromise is the key word here i guess.

but i agree-- to each his own. it's hard to hug your partner, let alone cuddle and have sex when you feel like beating the crap out of him/her :P. emotions don't always make a nice swift 180 degree turn no? :D
